Hey all 2011 kx250f timing is perfect at tdc valves adjusted good,  when trying to kick over it gets really hard to kick at certain points then kicks fine rest of stroke but can’t get full kick to even start it.  It’s something in top end feels like compression is to high is it possible auto decompression lever is worn out and not bleeding off enough compression.  Thanks

I’m late, but did you ever find a fix to this? Same thing going on with my 2009. I can always get it to kick when cold, still hard to do sometimes, but most of the time when it’s hot, it’s nearly impossible. Usually can get it to fire but it takes a lot
